Context Before

The real winner is the cabling vendors and active copper chip vendors in the supply chain who have a massive increase in volumes for leading edge 1.6T due to the prevalence of NVL36x2.

GB200 NVL576

Evidence

It will use 288 L1 NVSwitch5 ASICs (144 1U switch trays) located in the compute racks like NVL36x2, and it will use 144 L2 NVSwitch ASICs (72 2U switch trays) located on dedicated NV Switch trays.

Context After

Source: SemiAnalysis

② Atomic Claim

SemiAnalysis 預估 NVL576 使用 288 顆 L1 NVSwitch5 ASIC（144 個 1U trays）與 144 顆 L2 NVSwitch ASIC（72 個 2U trays）。
